B Ll N D S T O P SPECIFICATION forming part of Letters Patent No. 433,058, dated July 29, 1890.

Application filed December 17, 1889. Serial No. 334,122. (No model.)

To aZZ whom it may concern:

Be it known that I, ADAM VOLK, a citizen of the United States, residing at Lockport, in the county of Niagara and State of New York, have invented anew and useful Holder for Outside Blinds, of which the following is a specification.

This invention has relation to a holder for supporting in an adjusted, partially-open, or wholly-closed and locked position the pivotal slats of outside blinds.

The objects and advantages of the invention,together with the novel features thereof, will hereinafter appear, and be particularly pointed out in the appended claim.

Referring to the drawings, Figure l is an in' ner elevation of a section of an outside blind provided with a holder constructed in accordance with my invention, the same being in a locked position. Fig. 2 is a similar view, the slats being partially closed. Fig. :3 is a detail in perspective of the holder. Fig. 4: is a transverse vertical section, and Fig. 5 is a vertical longitudinal section.

Like numerals of reference indicate like parts in all the figures of the drawings.

The holder comprises three parts-a bracket, a cam-shaped hook, and a spring. The bracket is preferably formed of cast metal, is of oblong shape, and provided with a longitudinal vertical recess 1, forming an outer plate or wall 2, and an inner deeper securingplate 3, perforated at suitable points for the reception of screws a. The recess 1 is provided at its opposite ends and within the plates with shoulders 5, and sprung between the shoulders and located within the recess is a fiat spring 6, the ends of which abut against the shoulders. A pintle 7 is inserted transversely through the opposite plates, and upon the same is mounted a hook 8, the lower end of which is perforated, as at 9, for the reception of the pintle. Beyond the perforat ion, or at the lower extremity of the shank of the hook, the same is provided with a cam-face 10, and the upper edge of the hook is also provided with a curved cam-face 11, the lower cam resting upon the flat spring within the recess, and thereby being supported at any desired inclination.

13 represents an outside blind, which, as is usual, is provided with a series of transversely-disposed overlapping pivoted slats 14, connected at their inner edges by a rod or bar 15.

A holder constructed as described is secured by the screws 4 to the lower transverse rail of the blind, so that the upper cam of the hook will bind under the end of the rod 15 when the latter is elevated to its highest position, which is when the slats are closed. lVhen not in use, the hook is swung down within the recess, and when it is desired to close the slats and lock them against opening the adjusting-bar 15 is elevated, as before mentioned, the hook raised, and its upper cam-face pressed under the lower end of said rod or bar, whereby an opening of the slats without first removing the hook-shaped lock or holder is impossible.

Referring more particularly to Fig. 2 of the drawings, it will be seen that I may also employ my device as a holder for locking the slats partially or wholly open. Such is accomplished by swinging the hook to the left, then lowering the rod the desired distance, and releasing said hook, the spring serving to force the upper rear end of the same over and against the face of the rod.

From the above description it will be at once apparent that I have provided a most convenient fastener or holder for the slats of outside blinds, which holder or fastener is of exceedingly simple construction, can be cheaply and easily manufactured and assembled, aud this without hand labor or finish, except as to the usual assembling of the parts.

Having described my invention and its op eration, what I claim is- The combination, with an outside blind, its slats, and connecting-bar, of the herein-described combined lock and holder, the same consisting of a metal casting or bracket havin g a longitudinal vertical groove terminating at its opposite ends in shoulders, opposite plates or walls, one of which is perforated to form a securing-plate, a series of screws inserted through said plate, a spring located within the recess and having its opposite ends abutting against said shoulders, and a my own I hzwe hereto affixed my signature in hook pivoted between the plates and having presence of two Witnesses. a, lower cam end resting upon the spring and an upper cam -face adapted to be swung 5 against or under the lower end of the slat- Witnesses:

connecting bar, substantially as specified. OUTHBERT WV. POUND,

In testimony that I claim the foregoing as NATHAN M. CLARK.
